Dexter Preview Video: Get to Know the Season 6 Newbies - and Baddies!

Dexter‘s sixth season is right around the corner, yet still very little is known about the abundance of fresh faces popping up during the killer saga’s next cycle.

Thankfully, Showtime has put together a handy package of intros to the newcomers — including Colin Hanks, Edward James Olmos, and Mos — with some new footage thrown in for good measure.

Before educating yourself with the clip below, here are a few notable bites about each guest star:

Brother Sam | Played by rapper-actor Mos, Michael C. Hall says, “He is someone Dexter is initially pursing as a potential victim, but comes to realize Brother Sam has in a legitimate way rehabilitated himself by cultivating a relationship with God.”

Travis and Professor Gellar | Played by Hanks and Olmos, it appears these two are a package deal. “Travis represents a new bad guy,” Hanks reveals. “He believes he is doing the right thing and it is under the tutelage of Professor Gellar. The two of them have this relationship that is very… dangerous.”
